Improvement in shilling-brackets



UNITED TATES' JOHN M. SOHRAMM AND CHARLES T. SGHRAMM, OF PONTOOSUG, ILLINOIS.

IMPROVEMENT IN SHlNGLlNG-BRACKETS.

Specification forming part of Letters Patent No. 158,131, dated December 22, 1874; application filed November 21, 1874.

To all whom it may concern Be it known that we, JOHN M. and CHARLES T. SOHRAMM, of Pontoosuc, in the county of Hancock and State of Illinois, have invented a new and useful Improvement in Scaffolding for Shingling Roofs; and we do hereby declare the following to be a full and clear description thereof, which will enable others to make and use our improved scaffolds.

This invention relates to an adjustable seaffolding-bracket, which is to be placed on top of a roof of any pitch, and secured, by means of a set-screw, to the buttend of a shingle already laid, while forming a bearing for a scaffold, from which to work upon courses still higher up on the roof.

The invention will be readily understood by reference to the accompanying drawings, of Which- Figure I is a side elevation of one of the improved brackets as it appears in use on a roof. Fig. II is a front elevation of a'pair of the brackets on the roof as they appear while forming a scaii'old.

An iron foot-piece, A, is sharpened or flattened at its upper or forward end, so as to readily slip under the buttend of a shingle that has already been laid on the roof. This piece A is formed of a piece of bar-ironsay, one-quarter of an inch thick by an inch and a half wide and two or three feet long, more or less. To the top of this piece A is riveted another, which is marked B in the drawings, and which is of the same width as A. The forward end of B lies parallel with A, but is raised up from it by the elbow b, so as to form a slot, at, for the reception of the butt of the shingle, as shown in Fig. I. A set-screw,

O, which is threaded in B, is used to clamp the shingle firmly between the pieces A and B, and thus hold the bracket firmly to the roof. The back end of the piece B rises in a vertical arm, I), which has a set-screw, D, threaded in screw D. A stud, 11 in the lower end of the slot, is fixed in the arm [2 and prevents lateral displacement of the strap E. A horizontal bar, F, is pivoted or hinged to the top end of E at 00, so as to be easily thrown over on the roof ahead of its vertical support I) B, as shown in Fig. I, and thereby form a bearing for the scaffold-boards G, which are to be laid upon it. A short stud, f, at the back end of the bar F, prevents the scaffold-boards from slipping ofl' their supports to the rearward.

The bar F may be adjusted to a roof of any pitch, so as to lie in a level position, or in a position sloping toward the roof, by raising or lowering the piece E and securing it in the desired position by means of the set-screw D. Having described our invention, we desire to claim The adjustable roofing-bracket A. -13 O D E F G, constructed and arranged substantially as herein described and set forth.
